Below-Grade Waterproofing
The Details Matter
Co-authored by BEC SoCal's, Sophia Salah, and featured both on SGH's Website and inApplicator Magazine, this publication explores the complexity of below-grade waterproofing.
"When below-grade leakage occurs, it is often too late to directly address the root causes and can be very costly to repair, with limited options available to address subterranean leakage. Not only are below-grade leaks costly, time consuming, and challenging to address, but the waterproofing often cannot be accessed for direct repair except by extensive excavation, which may not always be an option. We are seeing more high-risk, sensitive spaces, such as vivariums, labs, medical offices, or spas, located within below-grade portions of buildings. How can we design and ensure that the below-grade waterproofing installation will remain continuous and prevent leakage to these sensitive spaces before it is too late? And if leaks do occur, how can we best address and stop the leakage without requiring extensive excavation? "
